AI Analysis

●●SolidSolve My ProblemSlick

Deploy-correlated query monitoring at $9/mo fills the gap between pgHero and pganalyze.

Strengths
  • •Deploy correlation tags each snapshot to the exact commit that was live.
  • •Health score aggregates cache ratios, bloat, vacuum, and connection saturation.
  • •Runs inside your Rails app—no separate agent or infrastructure to manage.
Weaknesses
  • •Database monitoring is well-funded with established players like Datadog.
  • •Free tier limited to 3-day history may not catch slow-building regressions.
Target Audience

Post Description

I'm a solo founder with a DBA background. Built this because pgHero only shows current state (no trends), and pganalyze starts at $149/mo. Lantern is a Rails gem that snapshots pg_stat_statements, tracks query performance over time, and tags each snapshot to the deploy that was live. Health score, query trends, deploy correlation. Free tier, $9/mo for 30-day history. Would love feedback.
